@sabrus Right now one loop in Mervis is about 30-60ms (can be seen while in debug mode in System status tab) but it also depends on the complexity of the application. You can also try to set a lower sleep ration in the task, eg. 5% in stead of 50% to make it little faster. There are some plans to make the whole runtime run much faster but I cannot promise anything...

@Alessandro
lbcm2835 is used to access I/O pins on the Pi. UniPis do not use GPIO to handle output. There are internal ARM processors which are connected to the Pi via an SPI bus that handle the system's IO. The easiest way to access the relays would be to install the neuron tcp modbus overlay as stated above and access the relays through a c++ modbus library.

Hello @Boy-Lenssen ,
list itemDIs are a galvanically isolated so unless the voltage and current will stay in the limits, you should be OK
Digital outputs & analog inputs and outputs are coupled together to common ground. So a there could be a risk of potential damage to these components when you are off the limits.
But do not worry the device is designed to provide maximum reliability when installed in the standard installation environment. And yes, replacing the device in case something goes wrong is the easiest and cheapest solution.

@bazza2000 Webcosckets and other web services are provieded by Evok API which is also available for Neurons.
But Mervis does not have these web apis, you can only create a TCP Modbus server and wire your internal variables to its registers.
Do not mix Evok and Mervis.

@matteos Hello, all certifications can be found on http://downloads.unipi.technology under the product folder.
Basically we have only certifications for Europe, so basically CE and Neuron products has a few more (according to the datasheet):
ČSN EN 6095‐1 ed. 2 ČSN EN 61000‐6‐3 ed. 2 ČSN EN 55014‐1 ed. 3 ČSN EN 55022 ed. 3 2006/95/EC 2004/108/ES 2014/35/EU 2014/30/EC
